Check how Andrew Sink creates a void background to 3D capture an apple by using photogrammetry and Agisoft Metashape software. Black matt blanket and clear focus, again, for it not to recognize any other points around the object. Turntable photogrammetry with DSLR camera. Mini LED-lit studios, for it not to recognize any other points around the object. Here are a few pointers on how to achieve good results with a professional photo camera. In case of a turntables, the location of the object pointers keeps changing, which causes a big mess for the processing software. Photogrammetry software greatly benefits from mapping the environment by measuring the distance between the object and points in the environment. Turntables – Poor Results When Using a Mobile Phone If the object has a lot of shadows, pay extra attention to the places affected and take more pictures. A cloudy day is better as there are no shadows that may cause a problem. The best 3D photoscans with a mobile phone can be achieved outside but it should be in the consistent lighting. On and off sunshine during capturing your object may also confuse the software. Use the Open Camera app for mobile phones. – Focus and capture all pictures manually. Otherwise, the photogrammetry software will be confused, and the photoscan will fail. To achieve this, cover them temporarily in some matt solution. – For shiny or reflective objects, the only way to capture them is to make them stop reflecting the light. If the object is accidentally moved during the photo session, it’s better to start all over. ![]() Make sure that your object stays still and is not shaking, changing position while taking the pictures. Some pictures may be blurry, as we are using the mobile camera, and then the photogrammetry processing software may reject without a known reason (for a casual user), so the more the merrier. ![]() As I mentioned earlier, capture now – process later. The Dolphin Lamp Standard was captured using a mobile phone camera, processed in Autodesk Re-Cap, and further reconstructed in Meshmixer.īefore going further, the first thing we have to learn is taking the pictures for the photogrammetry software. ![]() To my delight, I achieved a surprisingly good result when I uploaded zebra images to Meshroom, a free photogrammetry software. I liked using the ReCap software when processing the Dolphin Standard for the Scan the World, but paying a subscription fee for a rare casual photoscan doesn’t work for me. 3D Photoscan result of a zebra – texture and a pre-clean-up modelįor a few years, I’ve been putting off processing the images, and my free Autodesk ReCap Photo (previously ReMake) 30-day trial expired. It was a very nice experience and time well-spent in the fresh air in a park. Once on holiday, knowing the basics of photogrammetry, I captured a beautiful zebra (imitation) using my mobile phone. Photogrammetry – Capture Now – Process Later In this article, we will focus on what is possible to achieve by a casual user who wants to try photogrammetry for free/affordably with tools at hand. Of course, those who use expensive equipment like cameras with multiple lenses and process the results in a licensed software, may get better results and spend much less time for post-processing the images.
